1962 Ford 4000 SOS Help

[weeks22]

I 'm reaching out to see if there is anyone in Northwest Ohio (I'm in Fremont) that can readjust the number 3 band screw on my 1962 Ford 4000. We have tried following the manual directions with no luck. Thanks

Why don't you describe the situation for us? The adjustment is simple and straightforward, what is happening that doesn't allow the adjustment to occur?

We follow the steps to adjust the 3 band screw and we either are not getting the 2 reverses and gears 1-4 to engage or the tractor moves forward but with no power in gears 1-4 and won’t move in R1. If I put the front bucket down tractor stops.

Well in 1962 you have the possibility of two different SOS transmission one early and one late . The early one is an Overrunning Clutch version with a casting number of 312259 . The later version is the Direct Clutch type with the casting number of C0NN7006B . Both transmissions require different procedures for Band adjustments . Since you didn’t post any pictures or serial numbers I would guess you have no idea that there is two different types . But my guess is you have a 312259 early overrunning clutch type with a bad overrunning clutch and no band adjustments will cure that problem unfortunately .

These are the numbers that I have.

What is your serial number ? That transmission was produced in 1965 . The rear end center housing is 1962 but the later tractors have a lot of earlier parts in them . The serial number is on the left hand side just behind the starter on the flat surface of the transmission .

That is definitely a late model tractor with the better direct drive clutch transmission in it . I can also see that is the late model inching pedal on it . So the early over running clutch problem does not apply here . So as Pomester said you need to describe your problem in detail as to what is going on and what you done to it so far . Was this problem always there ? Did you just buy the tractor with this problem ? Did it work fine then this problem just happened ? All of those kinds of details .

This is the only other number I see in that area. In the 15 years I’ve had the tractor the gear shifting was never great. Good enough for what i used it for. The issue is entirely on me. I loosened the band screw thinking it was something else and that’s how I am in the situation currently. I got another torque wrench that is lighter than what we originally used. This one starts at 5lb instead of 10lb. The original one was heavier and it was hard to find the click of 10lbs. Later this week I will use the 5lb one and see if that helps us get it where it needs to be.

That’s not where I told you to look . The left side of the transmission BEHIND the Starter on the flat surface if it’s a gas engine it’s right under the air cleaner . How much did you loosen up the band screw ? One turn ? Two turns ? Or more .

This is a specific problem , not concerning a non running tractor . First you have to get your tractor running and see what your transmission does if anything BEFORE you touch it . Once you check the oil level in your transmission and make sure your traction disconnect if firmly engaged then see what it does .

Great to watch this thread for info but not to tie yours into it. As Tony posted get it running and see if you have a problem, it might not be the same as this one, it might not even have a problem. Once you know what is up with your tractor, it is best to start your own thread, so info does not get crossed up between the two tractors.

Hello Jim , I think the original poster loosened up the band screw too far and dropped the link out between the screw and the band . Just my guess right now .

That was my fear when he said that he loosened it up but didn't say how much.

 

[Tony Jacobs]

Well we will see if he has an honest answer in his reply .

 

[weeks22]

I am guessing that is what happened. I turned it more than a couple turns before I realized it wasn’t what I thought it was.

That was my fear when he said that he loosened it up but didn't say how much. Not sure what you mean by an honest answer, I pretty much said I messed it up. Guessing that to fix this would require splitting the tractor to get to it?

 

[Sean in PA]

Yes, splitting the tractor between the transmission and the rear end is the answer. Pretty much everything inside that transmission has to be removed from the rear, with the exception of the input shaft assembly. You'll probably only have to remove about half of the parts to get to the third band and put the link back in place.
